Well, I did find this link over the weekend and downloaded Max Davies excellent
routines for the IR reciever. However, despite over 10 hours of attempts, I was
unable
to get my preferred remote (a Toshiba) configured correctly. It was very strange
because
the test.c program correctly read out the data from my remote every time; I just
could not
obtain a rule that fit the data I was seeing. I am certain that with more fooling
around, I
will be able to get the Toshiba remote working. Mr Davies's routines are very
good and I
am grateful he has made them and his web page available so generously. I didn't
wish to
bother him for help however, since I found an RCA remote around the house from an
old
and long gone VCR. The RCA worked at once since that was what Max had to
experiment
with he says in his readme.
Perhaps I'll get the Toshiba running after more study, but for now the RCA is
doing the
job with Max Davie's ir files. (http://www.cam.org/~mdavies/HB/ir.htm) My 3 boys
and I have been running the handyboard around the house all day :)

| John, Like you, I recently purchased a Handy Board from Acroname. After doing quite a bit of research on the Internet to determine what my first experimental robotics platform should be, I felt confident that the Handy Board was the best choice. If (...)
